Answer:
3 hours: 38,250
1 day: 122,440
I’m not sure if this is exactly right, my brain gave out half way. Someone check my answer pls
Step-by-step explanation:
3 hours: 3 x 60= 900
900 divided by 20= 450
450 x 85 = 38,250
1 day: 24 x 60 = 1440
1440 x 85 = 122,440
Applying the definition of complementary angles, the value of x in the figure given is: 12
<h3>What are Complementary Angles?</h3>
Complementary angles are angles that give 90 degrees when added up.
(3x + 6) + 48 = 90 [definition of complementary angles]
Solve for x
3x + 54 = 90
3x = 90 - 54
3x = 36
x = 36/3
x = 12

The correct answer is:
C-old price was $170; new price is $159.12
You are correct for 18a through 18c. Nice work.
18a. True (think of it as 21 is less than 27)
18b. False; 0.4 is the same as 0.40
18c. True. Three dollars is much greater than 20 cents
18d. False. 1.9 is the same as 1.90 and can't be smaller than itself
18e. False. The two sides are completely diferrent numbers.
18f. True. The value 6.2 is the same as 6.20
--------------------------------
For problem 19, you have to make the denominators the same. So multiply top and bottom of the first fraction by 10 to go from 4/10 to 40/100
If 40 is in the first box, then 40+40 = 80 is the final numerator. If this is over 100, then 80/100 = 8/10 meaning that 10 goes in the other box.
solution:
If U=W-(54.5/6) then W=U+(54.5/6).
Assuming a one-for-one transformation, the mean for W is found by adding all the W data together then dividing by 79.
That is, Wbar=(w1+w2+w3+...+w79)/79.
But w1=u1+54.5/6, w2=u2+54.5/6, etc.
So Wbar=(u1+u2+...+u79)/79+(79×54.5/6)/79=Ubar+54.5/6=6.8+54.5/6=15.8833 approx.
The variance is unaffected by the transformation since variance is simply the spread of the data which doesn’t change.
Wbar=Ubar=1.8.
